This invention relates to sound propagating diaphragms.` Y

It is among the objects of the present invention to provide a novel and improved .5l diaphragm supporting structure and method of securing the diaphragm to the supporting structure. j

It is a further object of the present invention to provide an improved method of and means for securing and stretching ilexible diaphragms.

A further object of the present invention is to provide a novel and improved method of F and means for securing snares in combination with a sound propagating diaphragm.

Other important objects of the invention include the combination and interrelation of parts whereby the whole forms a simple,

drawings, in which y Figure 1 is a perspective view of one ernbodiment of the present invention; j

Fig. 2 is a transverse section through that form of the invention illustrated in Fig. 1, showing one step in the present method;

Fig. 3 is a fragmentary sectional view showing the invention after the steps of the method have been completed, and

Fig. 4 is a similar view illustrating the method of securing the snares and taken on lines 4-4 of Fig. 2.

Referring more particularly to the drawings, the invention is herein disclosed in an embodiment particularly adapted for drum heads or the like. It will be understood, however, that vthe method involved and the general structure used is readily adapted for use in connection with any sound propagating diaphragm and that changes'and modificationsof the present method or structure to adapt the same for other types of musical instruments is within the scope of the present invention. l

The structure involved in the present intaken in conjunction with the accompanying vention includes an outer ring 10, which may be arranged for securement in association rwith any desired supporting structure or musical instrument. f

Y In' the completed structure as illustrated in Figs. 1, 3 and 4, the diaphragm indicated at 12, is received within the ring 10,'its side edges 13 being disposed parallel with 'the side walls of the ring 10 against the inner face of the side walls of thel ring. A securingmember 14 is provided between which and the ring 10, the edges 13 of the diaphragm are secured', the upper edge 15 of the ring being crimped inwardly to secure the diaphragm and the upper edge of the member 14, locking the three portions securely together.

For assisting in securing rthe member 14 in the position illustrated,the lower edge 16 of the ring 10'is also bent inwardly to engage the lower edge of the member 14, wherevby the member is securely 'locked between the edges 15 and 16.

With the presentconstruction, it will readily be seen that snares may be secured beneath the diaphragm 12. Referring more particularly to Fig. 4, it will be seen that the snares 17 extend across the diaphragm and over the upper edge of the securing member 14 and pass between the member 14 and the edges 13 of the diaphragm, to be secured by the crimping action of the upper edge 15 of the ring 10.

ln the construction of the present invention it will be understood that the invention is not confined to any specic materials. In practice, the ring 10 has been formed of a readily bendable metal and the diaphragm is preferably formed of any suitable semiiiexible material, such as paper, cloth, skin or the like. In practice it has also been found practical to use cardboard or some stiff material for the member 14.

Throughout the device it is obvious that any desired materials may be used and that such materials are within the discretion of the manufacturer and form no part of the present invention.

In forming the present invention, the ring 10, as shown in Fig. 2, is provided with inwardly and downwardly extending edges 15 and 1G. rThe diaphragm is out and inserted within the ring 10, its side edges 13 lying parallel and against the inner face of the ring 10. VEhe member 11i is then inserted within the ring 10 and pushed upwardly to force the desired portion of the diaphragm between the ring 1() and the downwardly extending iiange 15. Then it is desired to use snares the same are placed beneath the diaphragm before the member let is inserted and thus are secured with the diaphragm 12. After the insertion of the member 14, to provide proper tensioning of the diaphragm 12 and to look the elements lei` and 12 securely together with respect to the ring l0, the edges 15 and 16 are finely crimped, thus providing the iinished device as illustrated in Fig. l.

From the foregoing it will readily be seen that the present invention provides a struc tural method of novel and improved characteristics and which is readily designed to conform with the demands of economie manufacture.

It will be understood that numerous changes and modiiications and the full use of equivalents in the structure and method involved do not constitute departures from the spirit or scope of the appended claim.

lVhat is claimed is:

A device of the character described, including a ring having inwardly disposed edge portions, a diaphragm having side portions disposed against the inner face of said ring, snares underlying said diaphragm with their ends at the inner surfaces of the side portions of the diaphragm, means for scouring said diaphragm and snares, said means including an annular member secured to said ring by said edge portions and securing said diaphragm and snai-es between itself and said ring.
